std.allocator.{make, dispose} is the type-aware interface. They 
don't currently do anything with regards to GC, and I don't think 
they really can except for the simplest case where A is exactly 
GCAllocator. If GCAllocator is part of an allocator composition 
or hidden behind IAllocator I don't think `make` can do anything 
about it.

Maybe GCAllocator simply isn't that useful.
